Stairs starting today!

The elevator is all set up and the weather's getting cooler, so I decided to start climbing the stairs to tackle my lack of exercise, even if just a little. However, my leg muscles don't function as well as they look, so for now, I'll take the stairs halfway and the elevator the rest of the way. I learned my lesson after climbing all 15 floors once and suffering from muscle pain for 4 days, so I need to prevent that. I excitedly thought 'This isn't so bad!' while climbing, but my legs hurt so much that night. I really overestimated my thighs. I've only made it to the 7th floor and my legs are already shaky like a newborn deer's. Damn this lack of exercise.
